An apparatus and a method for controlling a driving mode of a vehicle are provided to control the driving mode according to a short term driving tendency and a long term driving tendency. The apparatus includes a driving information detector that detects driving information to determine driving tendency and a controller that calculates a short term driving tendency index based on the driving. The controller operates at least one of an engine and a transmission based on the short term driving tendency index and calculates a middle term driving tendency index using the short term driving tendency index. A delay time is then determined using the middle term driving tendency index. The controller enters a sport mode based on the short term driving tendency index and releases the sport mode after delaying the delay time when the short term driving tendency index satisfies releasing conditions of the sport mode.

A control arrangement and a method for controlling a powertrain of a medium-duty or heavy-duty vehicle. The method comprises a step of, in response to one or more driver-initiated indicators, adjusting a currently predicted route for the vehicle to a new predicted route, said new predicted route being predicted in consideration of information related to the one or more driver-initiated indicators. The method further comprises a step of, determining a driving strategy for an upcoming road section of the new predicted route based on characteristics of said upcoming road section. Moreover, the method comprises a step of controlling the powertrain in accordance with said determined driving strategy.
